MICROANATOMY

Detailed explanation-1: -The part of your brain that runs autonomic functions is your hypothalamus.

Detailed explanation-2: -The main control center of the parasympathetic and sympathetic nervous system is present in the medulla oblongata or the brain stem. The hypothalamus also plays a crucial role in the regulating of this system and is therefore very important.

Detailed explanation-3: -The spinal cord runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part. This network of nerves relays messages back and forth from the brain to different parts of the body.

Detailed explanation-4: -The sympathetic system controls “fight-or-flight” responses. In other words, this system prepares the body for strenuous physical activity. The events that we would expect to occur within the body to allow this to happen do, in fact, occur. The parasympathetic system regulates “rest and digest” functions.
